Palantir is a tech platform that consumes data from their clients in return for providing high level data-driven insights. They assign FDEs (or consultants) to really learn the details of a customers data. Foundry allows them to get single pane view of the data in an org and they actually have both the tech and engineering skills to do the dirty data cleaning jobs.

For an extravagant fee, you give them your data, they clean it for you, and then those same FDEs can tell you interesting things that you should have known, had you actually done proper data architecture in the first place.
